If you have spent any time in American Mahjong circles lately, you have seen Oh My Mahjong tiles. Bright, illustrated, unmistakably modern — they are the sets that end up on Instagram, in boutique windows and on a lot of holiday wish lists. They are also expensive. A set of tiles alone runs several hundred dollars, and a full starter kit can cost more than a weekend away.

So is Oh My Mahjong worth it? Below we break down what the brand actually sells, what you get in a set, how the return policy works (read this part before you open anything), and how to save 10% with our code.

Who Is Oh My Mahjong?

Oh My Mahjong (often shortened to OMM) was founded by Megan, a player who first learned the game in college and fell back in love with it during the pandemic. Like many of the brands now shaping the American Mahjong revival, it started small: according to the company, Megan ran the early business herself and turned her garage into a shipping center before moving into a warehouse.

Growth came fast. The brand says it landed placements at Neiman Marcus and Tuckernuck within its first year, and it is now carried by hundreds of retailers across the country. Beyond selling sets, OMM runs the Mahji Mentor teaching program, which helps women build their own mahjong-teaching businesses, operates a teacher locator and a learn-to-play platform, and supports Alzheimer’s research.

That matters for buyers in one practical way: OMM is not a fly-by-night drop-shipper. It is an established brand with a customer service team, replacement-tile support and a large retail footprint.

What Oh My Mahjong Sells (and What It Costs)

The catalog is broader than most mahjong brands. Here is the lineup at a glance, with prices as listed on the official site in October 2026:

The brand also sells zippered tile bags, mat storage tubes, acrylic boxes, card folios, tablecloths and cocktail napkins, so you can coordinate an entire table in one order.

A Closer Look at the Tiles

Tiles are the heart of any set, and this is where OMM spends its design energy. Each collection has its own artwork across all suits. In the Seabreeze set, for example, the dots become colorful parasols, the bams feature herons and botanicals, and the Jokers are guardian lions — while the numbers stay easy to read.

Specifications (standard set)

• Tile count: 160 acrylic tiles
• Breakdown: 108 suit tiles (bams, cracks and dots, 1–9, four of each), 16 winds, 12 dragons, 8 numbered flowers, 10 Jokers and 6 blanks
• Tile size: 0.87″ W × 0.6″ D × 1.25″ H
• Included: dice/coin bag and 4 instructional cards

Two details are worth noting. First, the 10 Jokers and 6 blanks give you room for house rules and blank-tile play without buying extras. Second, OMM sets are acrylic. The care instructions are clear: keep tiles dry, wipe with a soft dry cloth, never submerge them, and avoid long exposure to direct sunlight, which can fade the colors.

How OMM approaches quality

Tiles are manufactured in China. According to the brand, a U.S.-based chemist runs routine performance testing on every shipment entering the United States, and OMM has added an experienced quality-control team on the manufacturing side. The company also says it tracks customer-reported issues daily so problems can be traced back to specific production batches. For a premium price, that level of process is what you should expect — and it is reassuring that the brand documents it publicly.

Starter Kits: Worth the Upgrade?

If you are building a set from scratch, OMM’s starter kits bundle everything into one coordinated look. The Seabreeze Starter Kit ($665) includes:

• Seabreeze tile set (160 tiles)
• Penelope neoprene mat, 33″ × 33″, in a reusable storage tube
• Structured tile storage bag
• Clear acrylic rack & pusher set
• Tile shufflers and 4 line finders
• 4 International Mahjong Cards

Buying the tiles ($400), a mat ($90) and racks ($110) separately already adds up to $600 before the bag, shufflers and line finders — so the kit is a fair deal if you genuinely need every piece. If you already own racks or a mat, buy tiles only and spend the difference elsewhere.

One important note on the card: OMM’s International Mahjong Card is the brand’s own format and supports play with blanks. Most American Mahjong groups and tournaments play from the annual National Mah Jongg League card, so check what your group uses before you assume the included cards are all you need.

Shipping & Returns: Read the Fine Print

This is the section most buyers skip and later regret. Oh My Mahjong’s policy (effective April 15, 2026) is stricter than many retailers:

• Free shipping on orders over $300.
• Returns within 14 days of delivery on eligible items — they must be unopened and in original packaging. Tiles must still be sealed in shrinkwrap with all cards, the dice pouch and dice.
• Opened items can be returned within 14 days for store credit only, minus a 15% restocking fee.
• Final sale: anything bought on sale, monogrammed items and gift cards.
• You pay return shipping, and returns need authorization by email first.
• Damaged, defective or wrong items: report within 7 days with photos; OMM covers return shipping.
• Broken tiles later on: OMM provides replacement tiles for sets that are still being sold.
• Holiday bonus: purchases between Thanksgiving and Christmas get an extra two-week return window after Christmas.
• Bought from a boutique? Returns go through that retailer, not OMM.

Our advice: inspect the box the day it arrives, and if you are buying a gift, keep it sealed until it is opened by the recipient.

Who Should Buy Oh My Mahjong?

Buy it if you play weekly, host often, or want a set that looks as good on the table as it plays. It is also one of the easiest „wow“ gifts in the hobby — just mind the return rules.

Skip it for now if you are a brand-new player on a budget. A basic set lets you learn the game first; you can always upgrade once you know your style. Check our discount codes page for other brands at different price points.
